5.2.5 MACHINE NOISE LEVELS
Noise levels were measured on a model SF600 + ST600 machine, with the cutting unit installed and functioning.
Test conditions (in accordance with the provisions of harmonized standard EN 1674:2015, Annex B):
- machine running empty at maximum speed, with the reversal of conveyor belts at approximately regular
intervals to simulate actual operating conditions, but without a pause between one reversal and another (i.e.
under more severe conditions than those that might occur during normal use)
- microphone positioned at 1.6 m from the floor
- distance of the microphone from the external surface of the parallelepiped envelope of the machine:
1000 mm ± 20 mm for points 1 - 2 - 3 - 4
200 mm ± 20 mm for point 5 (position in front of the controls)
- background noise of LAeq = 39.2 dB[A]
- duration of each measurement: approximately 30 seconds (not less)
The measurements were taken with a Class 1 integrating sound level meter
The following table shows the LAeq values (A-weighted sound pressure level) that were measured. Figure 48
shows the position of the points at which the measurements were taken.
The maximum error of the measurements is estimated to be in the order of 2 dB[A].
In the light of the values measured on the machine specified above and considering the great similarity between
the different versions of the machine, the A-weighted sound pressure level, LAeq, can reasonably be
considered to be less than 70 dB[A] for all the dough sheeters mentioned in this manual.
